by Lori Dajose, California Institute of Technology Graphical abstract. Credit: ACS Infectious Diseases (2023). DOI: 10.1021/acsinfecdis.2c00472 Caltech researchers have developed a new at-home test for COVID-19 that is more than twice as sensitive as current state-of-the-art antigen tests. While the test was developed for COVID-19, the technology can be used as a platform for designing tests to detect other...
